Proprietà magnetiche Magnetici in Ferrite anisotropa
Le proprietà magnetiche dei materiali ne determinano la suddivisione in gradi in base alle prestazioni. Questi valori rappresentano i valori dei campioni di materiale prima del taglio (rapporto dimensionale altezza/diametro = 0,7) misurati con analizzatore BH. Una volta effettuato il taglio dei materiali, le proprietà magnetiche dei magneti delle dimensioni finali differiscono da quelle dei materiali perché dipendono dal rapporto dimensionale e dalla temperatura ambientale. I valori riportati potrebbero essere modificati senza preavviso in seguito a migliorie, ecc.
